I own one, I have to say it has added a nice edge to my amped sound. Most bass amps have EQs that are great for electric, but crap on DB. I have also recorded with it and found it provides a better tone than a sans amp DI box. For the money I think it's a good deal. I also have the elements of my fishman attached to the top of my bass at the bridge feet instead of clamped to the bridge which has given me a bigger sound as well.
